Which mystic champion should I take to rank 5 and why?

Please help. After a long struggle I have gathered the resources required to rank 5 a mystic champion and these are the ones I have.

Magik for power control the whole fight. Keep the opponent in corner

I absolutely love magik but since I dupped my symbiote supreme for the third time I have been pretty inclined on using him

Magik can do her job at Rank 4. Symbiote Supreme gets even better.
